High Dynamic Range (HDR) is revolutionizing image quality, delivering vibrant colors, deeper blacks, and brighter highlights. Whether upgrading your home theater, enhancing conference rooms, or installing surveillance cameras, HDR enhances visual performance significantly.
But what exactly is HDR? Does your device support it? Why does some HDR content still look dull? In this guide, we will explain HDR in detail, answer common questions, and compare different HDR formats to help you select the best setup.
With SC&T's HDR-compatible solutions, you can easily achieve stunning visual effects. Let's dive in!
HDR (High Dynamic Range) enhances video by expanding contrast, color, and brightness. It allows for deeper blacks, brighter whites, and more vivid colors, creating more lifelike and immersive visuals. Unlike Standard Dynamic Range (SDR), which limits color and light ranges, HDR enables your display to show more detail in both dark and bright areas of an image, resulting in a more dynamic and realistic picture. This is especially noticeable in scenes with high contrast, such as sunsets or night-time environments.
Imagine watching a sunset: SDR might show a dull orange sky, while HDR reveals the glowing sun and clouds in the shadows. In audiovisual systems, HDR creates an immersive movie experience. In surveillance, it captures clear details in high-contrast scenes like nighttime store entrances.
HDR depends on:
HDR provides clear advantages in different scenarios:
However, using HDR in audiovisual setups requires compatible devices—displays, cables, and sources must all support HDR standards, leading to common setup challenges.
Here are common HDR issues and their solutions:
Not all TVs or cameras support HDR. Here’s how to check:
Solution: Upgrade to HDR-compatible devices (screens, computers/players/game consoles), noting that HDR10 requires HDMI 2.1 or DisplayPort 1.3 cables.
If HDR visuals seem dull or less vibrant:
Solution: Verify cables and settings to ensure proper HDR configuration.
Yes, HDR enhances the performance of analog, IP, and consumer-grade cameras in variable lighting. Key considerations include:
Dolby Vision and HLG (Hybrid Log Gamma) are two important HDR formats widely used in AV and surveillance, alongside HDR10.
HDR10 is one of the most widely adopted HDR formats, using static metadata to enhance the contrast and brightness of an entire video. It supports a 10-bit color depth, providing a noticeable improvement over standard dynamic range (SDR) by offering more vibrant colors and deeper contrasts. While it lacks the scene-by-scene adjustments of Dolby Vision, HDR10 is an open standard and doesn't require licensing fees, making it a more accessible option. HDR10 is supported by a wide range of devices, including many televisions, streaming platforms, and AV equipment, making it an ideal choice for both home theaters and surveillance applications.
Dolby Vision, developed by Dolby Laboratories, uses dynamic metadata to adjust brightness and contrast scene by scene or frame by frame, achieving precise color and light performance. Its 12-bit color depth (compared to HDR10's 10-bit) provides richer color depth, ideal for high-end home theaters or professional film production. However, Dolby Vision requires licensing fees, and device/content support is relatively limited.
HLG, developed jointly by BBC and NHK, is a free standard designed for live TV and surveillance. It uses static metadata, compatible with SDR and HDR displays without complex post-processing, suitable for real-time transmission scenarios like news broadcasts or dynamic scenes captured by surveillance cameras.
HDR10, Dolby Vision, and HLG each offer unique features suited for different applications:
HDR10, with its static metadata and wide compatibility, is a popular, cost-effective choice for streaming and gaming. Dolby Vision, with its dynamic metadata and up to 12-bit color depth, delivers superior picture quality, making it perfect for premium home theater setups, though it requires Dolby-licensed devices and comes with a higher cost. HLG, on the other hand, is tailored for live TV and surveillance, using static metadata and offering broad compatibility with broadcasting systems, making it a great choice for real-time content.
While HDR10 and HLG are free to use, Dolby Vision requires a licensing fee. Each format has its strengths, so choosing the best one depends on your specific needs and equipment.
HDR10 and HDR10+ are both based on the same core standard but differ in how they manage metadata.
HDR10 is widely supported and cost-effective, making it a popular choice for streaming and gaming. On the other hand, HDR10+ requires compatible devices to take full advantage of its dynamic features, limiting its availability but offering superior picture quality for premium home theater setups. Both formats are free to use, but HDR10+ provides a richer, more detailed visual experience if supported.
To fully leverage HDR technology:
1. Check Compatibility: Ensure your display, source, and cables support HDR (4K 60Hz requires HDMI 2.0 or higher).
2. Use High-Quality Cables: Choose high-speed HDMI cables (18Gbps) to avoid signal loss.
3. Enable HDR Mode: Activate HDR in both the TV settings and the source device.
4. Optimize Lighting:
5. Choose Compatible Devices: Opt for HDR-compatible displays, projectors, and signal transmitters for the best results.
HDR transforms audiovisual and surveillance experiences with vivid, lifelike visual effects. By understanding HDR10, Dolby Vision, HLG, and addressing common issues, you can unleash its full potential.

HDMI ARC (Audio Return Channel) was introduced with HDMI 1.4. This feature allows audio to be sent back from a TV to an audio receiver or soundbar through a single HDMI cable, eliminating the need for an additional audio cable.
HDCP is a digital content protection standard. When playing HDCP content, all playback devices need to be HDCP compliant and have compatible HDCP versions, or it may cause HDCP issues.
In this article, we will introduce what an HDMI® splitter and HDMI® switch are and delve into the disparities between them, covering their functionalities, applications, and distinctive audio-visual specifications. We will also highlight essential considerations when using these devices.
